ONION MAGGOT CONTROL WORK 



On the farm of Mr. A. Deguire, Cote-des-Neiges, Rd. 



Plot selected consisted of two and a half acres {2}/^) requiring fifty pans- 



These pans were set out and refilled on the same dates as Mr. Savoie's. 

 We were unable to get the final yields as in the owner's absence the hired help 

 lost the count and before this was discovered the onions were all in several 

 storages. The observations noted throughout the season brought out the 

 fact that this pest is not nearly so numerous as in the Rosemount "area. The 

 untreated plot was thinner in patches, but when pulled averaged larger in 

 size. The treated was estimated at 96% control while th« loss on the untreated 

 was not more than 10%. 



ONION MAGGOT CONTROL 



On the farm of Mr. P. Wattiez, Outremont, MontreaL 



Plot of 2 acres divided in half. The lower end treated with twenty pans 

 and the upper end left as a check. 



The pans were set out on May 26th. 

 Refilled June 2nd, 6th, 14th. 



On June 18th these plots were examined and found in the case of the treated 

 plot to be only lightly affected estimated at 8-10%. The untreated plot was 

 much worse, showing many blanks and wilted spots estimated as 15-20%. 



The whole crop was sold as bunch onions as soon as the bulbs were large 

 enough for kitchen purposes.
